FORCE-PUMP.

SPECIFICATION forming part of Letters Patent No. 263,294, dated August 22, 1882.

Application filed December 23, 1881.

To all whom @t may concern Be it known that I, M. FRANK MONELLY, a citizen of the United States, residing at Sterling, in the county of Whiteside and State of Illinois, have invented certain new and useful Improvements in Single-Acting Submerged Ilorce-Puin ps 5 and I do hereby declare the following to be a full, clear, and exact description ot the invention, such as will enable others skilled in the art to which it appertains to make and use the saine, reference being had to the accompanying drawing, and toletters or figures of reference marked'thereon, which form a part ot this specification.

My invention relates to an improvement in sin gie-acting force-pumps andthe novelty consists in the details of the construction of the head of the pump and the combination therewith of the handle and piston-rod, all as will now be more particularly set out and claimed.

It is intended that the cylinder ot' my pump shall be submerged.

The drawing is a vertical sectional elevation ot' my invention, showing the internal construction and arrangements of all its parts.

A, below the line o o, is an ordinary pump-' cylinder bored entirely smooth on its inner surl'ace, and above the line o o such cylinder is contracted inward to such a size as to render the top ofthe cylinder sufficiently small to permit of its being snugly fitted into the ordinary pump-stock, or, where provided with a thread, to be screwed into gas or other suitable pipe desired to be used in lieu of the common pumpstock. The cylinder A is divided into two portions at the line o o, and these are united, as now indicated in the drawing. In the plate B intervening between these ends are the openings covered by valves g g. The plunger D is fixed on the lower end ot' the piston-rod E. In this plunger are apertures i, which are covered by valves g.

Into the bottom of the cylinder A, I insert forcibly the hollow wooden plug F, which plug rests upon the bottom of the well and may be of any length desired. A strainer is placed in or near the bottom of the plug to keep gravel or other solid matter from entering the (No model.)

cylinder. On the upper end of this hollow plug I place the common clack-valve 7L. 5o

The piston E works perpendicularly through the center of plate B.

At such distance as I deem desirable above the dischargespout M in my pump I let into the pump-stock from the top, after cutting away the bore of the pump-stock sufficiently to let it in, the solid head G, which is made larger in circumference than the actual bore ot the pump-stock. This head rests upon and is screwed to the ledges formed by said cutting away ofthe upper part ofthe bore of the pumpstock. Through the center ot' this head is a holo which admits the piston-rod, but does not allow any more play therein than is necessary. lCast to the lower face ot' this head, and integral therewith, is the annular tube fic, which extends downward to any point desired above the discharge -spout. 'Outside of this tube w is the small V-shaped annular rim t, cast to the head Gr, and which may be 7o placed at any desired distance between the periphery of the head G and the tube w, being sufficiently near the periphery of the head Gr to enable me to drive said rim t solidly into the ledge formed by the cutting away of the upper part of the borein the pump-stock. Such head is also provided with the leg a, which slants outwardly and downwardly along a groove cnt into the pump-stock for that purpose to the outer surface of the pump-stock. It is provided with the earsp p and seatf. This leg is firmly screwed to the pump-stock. Through the ears p p is a bolt, which passes through the lower end otl the standard L, which oscillates upon such pin and Works in and is supported by the seatf. This standard L is placed upright and parallel to the pumpstock and piston-rod E, and is slotted at its upper end to receive the pump-handle O, to which it is bolted. The forward end of the pump-handle being bolted to the piston-rod and the standard L being free to oscillate upon the pin through the ears p p prevents all cramping of the piston-rod where it passes through the head Gr. On top of this solid head and around the hole for the piston-rod I place a small gasket, m, which Ihold in place by asmall annular plate, K, screwed through the gasket to the head Gr, the purpose of which gasket is to prevent leakage of air or Water around the piston-rod.

WVhat I claim as new, and desire to secure by Letters Patent of the United States, is

1. In a pump, the head Gr, provided with an annular tube, w, rim t, leg n, ears p p, seatf, and handle L, substantially as and for the purposes set forth.

2. In a pump, the head Gr, provided with all annular tube, wrim t, and leg n, as described, combined with the piston-rod E and handle 0, substantially as and for the purposes set forth. 15
